Compatibility Materials

Metals

 

  • Metals are not modified by radiation sterilisation because all the energy is dissipated, without risk of activation
    (Ref. : Manual on Radiation Sterilization of Medical and Biological Materials, Technical Reports series n°149, p.182, IAEA, Vienna, 1973).
    More information
  • Metals do not adsorb ethylene oxide (Ref.: Sterilisation of biomaterials and medical devices, edited by Sophie Lerouge and Anne Simmons, WP Woodhead Publishing, 2012).

Glasses

  • Glass stains with radiation at a low dose (a few kilograms).
  • Glass is a material that retains very low ethylene oxide quantities (Ref.: Sterilisation of biomaterials and medical devices, edited by Sophie Lerouge and Anne Simmons, WP Woodhead Publishing, 2012).

Ceramics

Ethylene oxide:

  • Compatibility related to absorption (attention to the level of porosity)
  • Compatibility related to process conditions

For radiation sterilisation, knowing that a material is generally formulated (risk related to extractibles and new formations), it is strongly recommended to carry out preliminary tests.

For its irradiation tests, Ionisos is chartered Research Tax Credit
